OpenAI-compatible API proxy to Claude. Drop-in replacement - change one line of code.
from openai import OpenAI
client = OpenAI(
base_url="https://claude.ai-platform.space/v1",
api_key="sk-cc-YOUR-KEY"
)
response = client.chat.completions.create(
model="sonnet",
messages=[{"role": "user", "content": "Hello!"}]
)
print(response.choices[0].message.content)OpenAI SDK, Anthropic SDK, LangChain, LiteLLM, curl. Any format auto-detected. 50+ model aliases.
Haiku (fast), Sonnet (balanced), Opus (powerful). All available via one API.
Token-by-token SSE streaming. Not fake chunking - real Claude stream events.
No subscriptions. Pay only for what you use. $5 free to start.
Multi-turn conversations with memory. Claude remembers context between requests.
Real-time usage stats, request logs, billing. Full visibility into your API usage.
Three developer tools you won't find in the official SDK — built to save you hours of boilerplate.
Visually assemble Claude requests without diving into documentation. Pick model, tune params, add system prompt, attach tools — get a copy-paste-ready JSON payload.
Claude often returns loosely-structured text. Our normalizer enforces your schema and guarantees a valid JSON response every single request — no more regex parsing, no retry loops.
Plug your personal Anthropic account into our SDK and use Constructor & Normalizer on top of your own Claude subscription — for testing and non-commercial work.
Built for developers who ship products on top of Claude — chatbots, AI agents, document analysis. We solve two specific pains: unstructured LLM output and slow prototyping of requests.
Pay per token. No monthly fees. No commitments.
